[Beast-Check] SSL/TLS BEAST Vulnerability Check

A small perl script that checks a target server whether it is prone
to BEAST vulnerability via target preferred cipher. It assumes no
workaround (i.e. EMPTY FRAGMENT) applied in target server. Some sources
said this workaround was disabled by default for compatibility reasons.
This may be the reason why RC4 ciphersuite was widely chosen as highest
preferred ciphersuite for the primary workaround.
